QUAD-BLOCK FOR SLUG-CASTING MACHINES.

Specification of Letters Patent.

Patented A ug. 1. 1916.

To all 'HILO'HL it may concern Be it known that I, I)AVID S. Kr:NNEnY,a citizen of the United States. residing at Brooklyn, in the county of Kings and State of New York, have invented certain new .and useful Improvements in Quad-Blocks for SlugCasting Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical machines. such as linotype machines of the general organization represented in the United States Letters Patent to U. Morgenthaler, No. 436,51 '2. wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the

composed line transferred to the face of a slotted mold, the mold filled with molten metal to form a slug or hnotypa against the matrices which produce the type characters well. known quad blfitk, wherein l mount a series of matrix sections to make up the line, the sections being readily removable or interchangeable to permit the composition of any desired matter.

In the accompanying drawing, I have shown my invention merely in preferred form and by wav of example and as applied to a machine of the class stated, but obviously it is susceptible of various other modifications and adaptations which will still be com )riscd within its spirit, and it may be appiied to type ordies as well as to matrices.

Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are specified in the claims.

Referring to the drawing:

Figure 1 is a perspective .riew of my impiioved quad block. Fig. 2 is a vertical section thereof; Fig. 3 is a section on the line 33 of Fig. 2; and Figs. 4 and 5 are perspective views of two detached matrix sections. one having a character impression in its edge, and the other being plain so as to act as a spacer.

My improved quad block comprises a body portion A of the usual form, so as to be supported in a linotype machine in the regular Way for cooperation with the mold. In its front face the. body portion A is provided with a longitudinal groove or recess A containing a series of 1etter-character sections X arranged in word groups and other quad sections or spacers Y, inter 'iosed between the word groups and also arranged at the outer ends of the groove. When thus assembled, the parts constitute in effect a single composite matrix equal in length to that oi the line required. It will be noted that the grove A is of dove-tail shape and that the matrix ections are made to correspond. so that when they are assembled in thegroovc. they will be held against edgewisc displacement and with their front or operative edges flush with tl" front face of the body portion, thus presenting a smooth surface which fits tightly against the mold during the casting operation. However, to permit the ready insertion and removal of the matrix,sections. the greater portion of the upper wall of the groove A is cut away, it being closed by a plate B pivoted to the body portion A. at B, and held in firm but yielding engagement with the upper ends of the inserted matrix sections by strong leaf springs A fastened to the body portion A and located within recesses A in the rear face thereof. -By swinging the plate B upwardly to the position shown in Fig. I, complete access may be had to the matrix sections, which can thus be readily removed or interchanged, either independently or in group. To permit their easy removal, the sections X and Y are formed in their ends with notches X and Y to receive some suitable instrument or to afford a gripping surface for the fingers. It desired, the plate B may be provided With a grip portion B to facilitate its movement.

W hen the sections X are assembled in the matrix body, it is necessary that their characters be inverted, or stand with their tops pointing downward, this being their proper and custmnary position. In order to insure this result, the sections X are provided in their edges with notches X adapted to fit over a longitudinal bar or ledge A fixed to the body portion A and projecting into the groove A the location of the notches X being such that the ledge may enter them only when the matrix sections are inserted ilrthe groove in the proper position, that is, with their characters inverted. The same necessity, however, does not exist in case of the spacers Y, which can be set in the groove with either end up, they being provided in their rear edges with notches Y of such ex tent as to fit over the ledge A in either position. In this connection it will also be noted that the spacers Y are formed in both ends with the notches Y to permit their ready removal when either end is uppermost.

l have herein shown and described my in vention merely in preferred forin and'by way of example, and it will be apparent that many changes and variations will suggest themselves to those skilled in the art without departure from its scope. Thus, the details concerned in the support of the matrix sections, or in their independent re moval, or in their proper location in the matrix body, as well as the form of the ma trix sections, or the particular characters contained therein, etc., may be variously modifiedwithin the province of the skilled mechanic.

Having thus described my invention, its construction and mode. of operation, what I claim and desire to Secure. by Letters Patent of the United States is as follows:

1. A quad-block for slug casting machines comprising a body portion formed with laterally projecting ears to adapt it for support in such machines, and a changeable matrix sections supported therein side by side, the whole constituting an assembled matrix line for use in said machine.

2. A quad-block for slug casting machines con'iprising a body portion formed with laterally projecting ears to adapt it for support in such machines, and a series of independently removable matrix sections supported therein side by side, the whole constituting an assembled matrix line for use in said machine.

3. A quad-block for slug casting machines comprising a. body portion formed with laterally projecting cars to adapt it for support in such machines, and a series of. matrix sections supported therein side by side, some of the sections containing letter-characters and arranged in word groups, and others be ing plain and interposed between the word groups to act as spacers, the whole thus constituting an assembled matrix line for use in said machine.

4. A quad-block for sl ug casting machines comprising a body portion formed with latseries of inter-,

erally projecting ears to adapt it for support in such machines formed in its front face with a longitudinal groove or recess and a series of matrix sections supported in said groove with their forward edges flush with the front face of the body portion, the whole constituting an assembled matrix line for use in said machine.

5. A quad-block for slug casting machines comprising a body portion formed in its front face with a. longitudinal groove open at one side, a series of matrix sections supported in the groov and a locking plate se cured to the body portion to close the groove at its open side and hold the matrix sections therein against removal, the said plate being movable at will from its operative position to permit the removal of said sections.
